Nonlinear Analysis of Spur Gear Pair with Time-varying Mesh Stiffness [PDF]
This study presents nonlinear analysis of single degree of freedom spur gear pair with time-varying mesh stiffness. The backlash is approximated using nonlinear term. The periodic steady-state solutions of the nonlinear system are obtained by closed-form expressions using the method of multiple scales. The stability and forced vibration response of the

Extraction and use of frequency-domain relationships between time-varying gear meshing properties and diagnostic measurements [PDF]
In gears, the key diagnostic information is carried in the gearmesh stiffness and geometric profile errors. These two key gear meshing properties combine nonlinearly with rotations and displacements of the gear shafts to produce a time-varying gearmesh ...

Study of the Influences of Transient Crack Propagation in a Pinion on Time-Varying Mesh Stiffness [PDF]
Cracks in a cracked gear may further propagate by a tiny length in a very short time for several reasons, such as material fatigue and load fluctuations. In this paper, this dynamic process is defined as transient propagation of cracks. This research aims to calculate the time-varying mesh stiffness of gears when transient propagation of cracks arises,

The influence of time-varying mesh stiffness on natural characteristics of planetary gear system
Abstract Modal property is the crucial factor that can influence the vibration characteristics of the planetary gear system. Previous studies used time invariant mesh stiffness (TIMS) to study the natural characteristics. However, with the rotation of the gear, the meshing stiffness will change periodically which will lead to changes of ...
